oil process water treatment Applications

For most oil sand recovery is accomplished with in-situ thermal processes like Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS), where steam and chemicals are injected to the liquefy the bitumen. The treatment and recycling of the produced water used in this process has a direct impact on the cost of oil production. Aquatech provides water treatment technologies that includes the recycling of the produced water used the process which has a direct impact on their the cost of oil production.

Kurita Water Solutions provides oil refineries and petrochemical plants with all the chemical additives used directly in the process, to fight the problems caused by the composition of the crude oil and the intermediate products. In oil refineries and petrochemical plants the goal is to improve efficiency and to optimise the production capacity.

In a Steamflood Enhanced Oil Recovery (EOR) process, steam is injected in the well, lowering the viscosity of heavy oil suitable for extraction through the production wells. The fluid from the wells is a mixture of oil, water and gas and goes through a separation system to separate the three. The separated produced water is heavily contaminated with dissolved solids and hydrocarbons.
Aquatech’s Steamflood Enhanced Oil Recovery (EOR) Technology offers the integrated solutions for the treatment EOR produced water for boilers, generating a purified product that can be reused for the production and injection of steam. Our turnkey approach to treatment includes coordinating the logistics of wastewater removal off-site and any sludge disposal.

Deposits and corrosion as well as undesired emulsion, foam and toxic gases impact the operation and the occupational safety in refineries. Kurita provides tailored treatment concepts to increase the operational and the occupational safety. Our product lines and technologies are based on decades of experience in process treatment and they contribute to reduce your total operating costs.

Compressor condensate wastewater is generated during hot and humid weather as part of the process of condensing shop air to provide compressed air for machine tools. Typically, these waste streams are transparent with a slight floating layer of oil. Compressor Condensate wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.

The food processing industry also has a broad range of applications for oil skimmer and waste oil recovery technology. From wash water sumps to waste water treatment pits, the AMBAR rope skimmer is versatile enough to be used in all types of applications and outperforms tube oil skimmer products.

Oil and gas companies, whether in coastal or offshore settings, use water in various stages of production and for drinking and sanitary purposes. Process water, feed water and wastewater requires disinfection and filtration treatment prior to use, reclamination or discharge. De Nora Water Technologies has been providing water and wastewater treatment solutions to the oil and gas markets for more than 25 years.

Schwing Bioset, Inc.`s technical expertise and innovative approach to the design of Fluidized Bed dryers, coolers, and conditioners has resulted in Schwing Bioset fast becoming a preferred partner of companies processing municipal solids and companies processing coal. The versatility of Schwing Bioset`s piston pumps allow them to be used in many industries to pump a wide range of materials such as oil sludges, dredging spoils, food wastes, and coal slurries. In fact, Schwing Bioset pumps are so versatile they can pump just about anything that can be fed into them.

The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures

At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

Sulfide Odor Control
Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L.
Sulfide Treatment Alternatives
There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application.
Treatment with Hydrogen Peroxide
While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective.
H2O2 may control sulfides in two ways, depending on the application:
Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and
Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.

You refine the fuel, we’ll remove the odors. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public. Ecosorb odor removal products may be used in a variety of areas around the refinery including water treatment facilities, sludge ponds, sulfur recovery units, and API separators. To remove odors during tank cleaning and maintenance operations, portable dispersion systems can be used in the immediate work area to control malodors. Ecosorb products can be directly injected into flues and stacks and may be used as a substitute scrubbing solution in some applications.
